It is great to see so many pictures of your DONs for comparison. I hope you wont mind me posting pics of my Speedmaster after I get it back from Time Tech.
Kevin at Time Tech in Texas fixed the problem with the pushers. Great guy but is shying away from Cal 321 watches. He asked me not to run the watch as it is pretty dry. His next opening to service is February. Should be home next week. Then I'll put the Speedy in the cooler (not literally).
This is an amazing watch! Actually, there are many on this thread that are simply remarkable. Wish one of them was mine!
This is not perfect, but it's not bad either. Mind you, the DON is not the thing I like the most about the watch
